128层螺旋CT对急性肠梗阻的诊断价值探讨

目的:比较128层螺旋CT与X线平片对急性肠梗阻的诊断价值。方法:临床拟诊断为急性肠梗阻的患者首先行腹部立位X线平片筛查,确诊急性肠梗阻患者进一步行CT检查。比较两种诊断方法对梗阻部位、梗阻原因的差异,并比较手术诊断符合情况。结果:128层螺旋CT与X线平片分别对梗阻部位、梗阻原因、绞窄的诊断差异有统计学意义(P<0.05)。有20例患者进行了手术治疗。CT发现梗阻部位17例,与手术不符合:1例结肠梗阻误诊为空肠梗阻,1例回盲部梗阻误诊为空肠梗阻。病变性质不符合:1例肠结核误判为肠肿瘤,1例肠系膜内疝误诊为单纯肠扭转,2例肠粘连性梗阻诊断为原因不明。结论:128层螺旋CT可以清晰显示梗阻部位,对肠梗阻的定性诊断也有一定价值。

Objective： To compare a 128 - slice spiral CT and X - ray diagnosis of a- cute intestinal obstruction value. Methods： The clinical diagnosis of acute intestinal ob- struction patients did X - ray screening first, then CT scan. Compare the two diag- nostic methods on the part of the obstruc- tion, obstruction causes the difference, and compare the surgical diagnosis. Results：the two methods found the obstruction part of the cause of obstruction, the diagnosis of strangulation difference was statistically sig- nificant（ P 〈 0.05 ）. 20 patients underwent surgery. CT showed the site of obstruction of a total of 17 cases, two cases of surgery do not meet, as one cases of lesions does not meet the patients with mesenteric hernia misdiagnosed as simple volvulus, two cases of intestinal revolves with obstruction diag- nosed as unexplained. Conclusion：The 128-slice spiral CT can clearly show the site of obstruction, the qualitative diagnosis of intestinal obstruction.
